Medical marijuana became legal in the state of New York last weekend, and this 14-year-old played a huge part in getting the bill passed.

In this exclusive video for US site Elite Daily, Oliver Miller and his mum Missy show exactly why they believe the legalisation, making New York the 23rd state to allow consumption of the drug on medical grounds, needed to happen.

Marijuana is a class B drug in the UK, making it illegal to ‘possess cannabis in any form’.

Oliver, of Atlantic Beach, New York, suffered a stroke while in the womb which has left him severely handicapped. As a result, he suffers hundreds of seizures every single day. Seizures which, according to medical research, could be eased by cannabis.

This video of him and his mum will touch you (and give you a serious case of goosebumps) regardless of your stance on drugs.
